Be shunted to the various pieces of system, thus the radiofrequency signal for the not homologous ray that same system can be received by the present apparatus into
Row filtering, is effectively reduced the volume of radio frequency system.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for the combining filtering branch apparatus that the embodiment of the present invention proposes.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, the embodiment of the present invention proposes a kind of combining filtering branch apparatus, including main cavity 1；
It is successively arranged combining cavity 2, filtering cavity 3 and function in main chamber body 1 and divides cavity 4；
Combiner circuit board is equipped in the combining cavity 2, the input terminal of the combiner circuit board is connected with setting and exists
The output end of the input adapter 5 of the side of main chamber body, the combiner circuit board connects the filtering cavity；
The filtering cavity 3 is provided with filter circuit, and described filter circuit one end connects the defeated of the combiner circuit board
Outlet, the other end connect the function and divide cavity；
The function divides the input terminal of cavity 4 to connect the filter circuit, and the other end, which is connected with, is arranged in main chamber body
The out splice going splice 6 of the other side.
As it can be seen that the embodiment of the present invention propose combining filter branch apparatus, main cavity include combining cavity, filtering cavity and
Function divides cavity, not the radiofrequency signal of homologous ray be input to combining cavity be combined after be output to filtering chamber be filtered, then
The various pieces of system are shunted to by function sub-chamber, thus the not homologous ray that can be received same system by the present apparatus
Radiofrequency signal be filtered, the volume of radio frequency system is effectively reduced.
In a preferred embodiment of the invention, filter circuit includes multiple resonators.
Dielectric filter is to utilize the low-loss of medium ceramic material, high dielectric constant, frequency-temperature coefficient and thermal expansion system
Number is small, can bear what the features such as high power designed and produced, by several elongated resonators longitudinal direction plural serial stage or the ladder track of parallel connection
Road is constituted.Its main feature is that insertion loss is small, resistance to power is good, narrow bandwidth, it is particularly suitable for CT1, CT2,900MHz, 1.8GHz,
